1 Claim.

This invention relates to a combined heating and cooking unit and itgenerally aims to provide a structure whereby a range or the like may beused in the ordinary manner, and in addition may have its heat impartedto a hot water heating system.

The more specific objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a horizontal sectional view through an improved stoveaccording to the invention;

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a front end elevation of the heating unit;

Figure 4 is a rear end elevation of the heating unit;

Figure 5 is a detail section taken on the line 5-5 of Figure 3; and

Figure 6 is a detail section taken on the line 6-6 of Figure 5.

Referring specifically to the drawing wherein like reference charactersdesignate like or similar parts, the range or the equivalent is shown at[0 of which II is the oven. According to the invention, an improved firebox structure is provided at I2 being generally rectangular and hollowso that it may retain water, the front having an opening I2 therein inline with the door M of the stove or range. The box 12 has a tapered potl3 wherein the coal or fuel is deposited and one side wall is cut awayadjacent the top as at l5, so that the products of combustion may passthrough the usual space I6 above the oven and escape through a dischargeflue or chimney IT. The fuel is supported within the pot l3 by means ofa coil l8.

Water supplied from any suitable source enters the coil I8 and the spacewithin the fire box l2 through pipes l9 and it leaves such space and thefire pot by means of pipes 20, leading to hot Water heating systems orthe like. It will be noted that portions of the lower wall of the firebox 52 are arched as at 21 so as to fit over the coils l8 and further itwill be noted that the pipes l9 and 29 include connections 22 and 23where- 5 by the coils may be detached for inspection or replacement.

In order to extract the maximum heat from the fuel and utilize it in thesame hot water heating system in connection with which the fuel box 10i2 is used, or for use in any other desired way, an auxiliary coil 2%generally of skeleton form, rests upon the top of the oven II. This coilhas communicating transverse tubes 25- and longitudinal tubes 26, thelatter preferably being pointed at 15 the top so that soot and asheswill less readily fall and rest thereon. The structure also enablesready cleaning by means of a scraper or the like. The water to the coils25-26, is supplied from any suitable source through a pipe 2] and itleaves or circulates therefrom through a pipe t will be noted thatcertain lugs 29 rise from parts of the coil 2526 and support the top 30of the stove. 25

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention:

A cooking and heating stove having a fire box, 30

a rectangular, hollow water container surrounding the fire box, saidfire box being open at top and bottom, one end portion of said containerhaving notches in its lower surface, a water supply pipe connected tothe container, a coil within the fire 35 box having an inlet pipeconnected to thefirst mentioned pipe and having an outlet pipe, saidinlet and outlet pipes being disposed in said notches whereby the coilis arranged above the base of the container, the walls of the fire box40 fiaring downwardly and inwardly, and one of the side walls of thecontainer being depressed to permit the discharge of products ofcombustion.
